Ecological extinction explains how turbulence dies

As anyone who has experienced turbulence knows, its onset and departure are abrupt, and how long it lasts seems to be unpredictable. Fast flowing fluids are always turbulent, but at slower speeds the flow transitions to smooth and predictable (laminar) with intermittent patches of turbulence. In the human body, transitional turbulence can be deadly. Near the transition to turbulence, violent oscillations between laminar and turbulent blood flow can lead to aneurisms that rupture the arteries in
